IMPROVEMENT IN CARDlNG-MACHINES.

Specification forming part of Letters Patent No. 127,566, dated June 4,1872.

.Specification describing certain Improve- .ments in Carding-Engines,invented by FRED- ERICK T. CHASE and J oHN H. PLATT, of Dudley, in thecounty of Worcester, State of Massachusetts.

and bring more up to be subjected to the same action. To accomplish thiswe heat the teeth of the strippers by the use of steam in them or by anyother efficient means, and place a holding evener-bar or surface partlybetween them and the workers in such close-proximity to the latter thateach bar and worker shall retain a hold on the stock passing from theworker to the stripper, and hold it while the heated teeth of thestripper comb it by passing through it. These teeth we prefer being madewith less hook than the common form of card-teeth, as being less liableto snatch The heat of the bers softens and relaxes the natural curlwhile the teeth straighten or comb the bers before the last end passesthe hold, there lbeing -no necessity for any stopping of the wool tocomb or straighten it, but only a slower motion of workers and strippersthan has been commonly used.

In the accompanying drawing, Figure 1 is an elevation of a card with ourinvention applied. Fig. 2 is a section of same parts on a larger scale,and hereinafter more particularly described.

A A is the frame; B, the cylinder. C C C C are the workers; D D D D, thestrippers; E E E E, the evener-bars adjusted partly between thestrippers and workers, and holding with the latter on the wool while itis combed and straightened by the heated teeth of the strippers, asshown in section in Fig. 2. G is the feed-roll, H its shell, and F thetumbler, and J, the pipe carrying steam to the tumbler F and strippers DD D D, a similar pipe on the opposite side suficing to carry oft' thewaste steam and water.

The appliances to accomplish this bein g well known in mechanics, noparticular description is deemed necessary. We are aware that heat hasbeen used in the first feed-rolls and roller of what is commonly calleda card-breast or preparingmachine,77 to prepare the wool for the tineteeth of the rst breaker, as shown in Holdens patentffin England, datedJanuary 30,1857, and that steam has been introduced into perforatedfeed-rolls to moisten the wool. These we do not claim.

What we claim as new, and desire to secure by Letters Patent, is-

The combination, with the holding mechanism, composed of the evener-barand worker, or their equivalents, of a stripper, or its equivalent, theteeth of which are heated by steam, substantially as above described.FREDERICK T. CHASE.
